The World Radiation Monitoring Center (WRMC) is the central archive of all Baseline Surface Radiation Network measurements.
Since 2008-07-01 the WRMC is hosted by the Alfred Wegener Institute.
Data were transferred to AWI from the original ftp-site at ETH Zurich until about 2008-03-01.
The data within the WRMC are read account restricted.
Read accounts for both - PANGAEA and ftp access - can be obtained from the WRMC for free.
